CONTAINER.

Specification of Letters Paten Patented Feb. 20, 1917.

Application filed June 28, 1913, Serial No. 776,202. Renewed July 3,1916. Serial No. 107,465.

To all whom it may concern:

Be it known that I, CHARLES W. SHEVLIN, a citizen of the United States,and a resident of Chicago, in the county of Cook and State of Illinois,have invented a new and useful Container, of which the following is aspecification.

My invention relates to the provision of a container, or tubularreceptacle made from a tissue infused or impregnated with a suitablesubstance to render the article as a whole'impervious to air, moisture,or liquids,

. so that the receptaclemay be used either for containing liquids andgreas substances, the -same being proof against lea age of the mostpenetrating of such substances; or for conprote'cting same from theaction of the exterior air or moisture.

As is known, when fibrous articles are impregnated so as to render themimpervious to water, theyare rendered unsuitable for gluing with any ofthesubstances now employed for such a purpose. Besides this,

glue or any of the known adhesives arenot desirable substances to use inthe presence of moisture, as the moisture with the glue substances,besides impairing their adhesive properties, affords conditionsfavorable to the growth of bacteria, which growth is ordinarily known asputrefaction. The use of,

such metals as are available is hardly less undesirable than glue, asthe available metals in the resence ofair' and moisture undergo oxiation which is liable to cause variouschemical changes in substancespresent and subject to such action.

It has, therefore, been one of the problems whicl-r confronted me, andone of the objects of my present invention, to arrive at a method offorming such a container, with- .out using any of the known adhesives-oravailable metals for securing the outer end of the outer fold or casing,so that it will not be liable to disengagement. It will be understoodthat the integrity of my packet e in handling largely depends upon "t estrength of the outer casing, as the impre nation of the tissue causesconsiderab e weakening, and the impregnating materials, while permittingsome degree of adhesion between successive layers, are not what are Igenerally regarded as" adhesives.

I attain the above objects by a preferred form of cc ntainer illustratedin the accompanying drawing, in which' Figure l is a central verticalsection through a completed container; I

Fig. 2 is a fragmentary perspective view of the outer casing of thecontainer in position for lo1king, the impregnated liner being shownpartially withdrawn; and

Fig. 3 in a fragmental plan of the two ends of the casing portion of theblank.

Similar reference characters designate similar pal ts throughout theseveral views. In carrying out my invention I take a sheet of fibrousmaterial, as designated by the numerzl 5, preferably a suitable grade ofpaper, of a length and width commensurate with the size and length ofthe container required, and, at one end thereof, I form a spear head,5", preferably of the shape show: 1 in Fig. 3. It will be noted that theedges of the blank are tapered at 5, to

a the inner ortions of the shoulders of the spear head 5, so that whenthe casing is made into t cylinder, the edges 5 will be disposed sp:rally in the circumference of the cylinder, aid in this way will becaused to remain snugly in position, and will not be liable to be rolledback through handling or accident. It will be seen that thisconstruction will hcld the edges 5}? in place even if no adhesivewhatever were used.

At a suita ble distance from the spear head 5", to form a casing'of thedesired size, I provide a trans verse slot 5, into which the said spearhead 5 is forced, the shoulders 5 of the said spear head binding same inplace.

The lining; portion of the blank, 6, having first been impregnated with,in this lease the linin thus causing them to adhere to-' gether. heinner portion or lining is thus impregnated while the outer casingremains only slightly coated and unimpregnated, thus rendering thepackage walls moisture proof, while, at the same time, the outside wallretains its original strength, the spear being permanently sealed inplace between the inner face of the casing and the outer fold of thelining.

I-prefer to make the two end closures, 7 and 8, as follows: A circularsheet of paper or tissue is formed in a die so as to have a turned upouter edge or periphery, 8*,

10 making a cup-shaped member. One of which cup-shaped members, afterthe same has been impregnated with paraflin, or other suitableimpregnating substance, is then inserted or forced into the cylinderfrom each end, as very clearly shown in Fig. 1. The

form supporting the bottom member, 8, being heated, the parafiin iscaused to adhere or unite with the impregnated lining at that point,and, to further insure its stability,

staples, 9, are driven through the cylinder and the flange 8 of thebottom member 8 at suitable intervals upon its periphery. The metal ofthe staples in this case is sufficiently removed from proximity to thecontents of the container as to be free of fear of the contaminationthereof. To still further make the union complete between the flange,8", of the bottom and the inner lining, 6, at their point of contact, asmall quantity of melted parafiin is allowed to run into the crevicebetween the members while they are still hot, and there allowed to coolwith them. As the mandrel upon which the top, or member 7, is inserted,is not heated,

the side or flange 7 does not adhere to the lining 6, but is-merely heldin. place by a force .fit, thus allowing'its removal without in any waymarring or injuring the properties of the "package as a whole. But, in

40 case it is desired to have the package absolutely sealed, the top maybe heated and p sealed the same as the bottom after the contents havebeen placed inthe container.

For further: protection, another cupshaped member, 10, formed exactlylike the cup=shaped members 7 and 8, with the exfception that it issufliciently larger 'in diameter to fit over the ,outside of thecylinder, may thenbe placed over the end holding the cup shaped member7. Such an additional cover, 10, not only afi'ords greater protectionfrom contamination, .but also provides the space 11, which serves to protect the top of the contents ofthe package from radiation, and intowhich space 11 may be placed directions for use of the contents andadvertising material.

Having described my invention, what I claim as new and desire to secureby Letters Patent is 1. A cylindrical container comprising a blank offibrous material, one end of which said blank is formed into a spearhead, a transverse slot being provided in said blank to receive saidspear head to form a circn: lar wall or casing for said container, theremainder of said blank being impregnated with an impervious solidifyingsubstance and disposed inside of said casing so as to contact therewithand adhere thereto by reason of the solidification of said substance.

2. A cylindrical container comprising a blank of fibrous material, oneend of which said blank is formed into a spear head, a transverse slotbeing provided in said blank to receive said spear head to form acircular wall or casing for said container, the remainder of said blankbeing impregnated with wax and disposed inside of said casing so as tocontact therewith and adhere thereto by reason of the solidification ofsaid wax.

3. A cylindrical container comprising a casing formed of a blank offibrous material, one end of which said blank is formed into a spearhead, a transverse slot being provided in said blank to receive saidspear head to form said casing, and a fibrous lining for said casingbeing impregnated with an impervious solidifying substance and disposedinside of said casing so as to contact therewith and adhere thereto byreason of the solidification of said substance.

4. A cylindrical container comprising a casing formed of a blank offibrous material, one end of said blank is formed into a spear head, theedges of said blank being tapered from the broadest part thereof-to theshoulders of said spear head so that said tapered edges will be disposedspirally upon the outside of the finished container, a transverse slotbeing provided in said blank to receive said spear head to form saidcasing", and a fibrous lining for said casing being impregnated with vaXand disposed. inside said casing so as tocontact there'witl1 and adherethereto by reasin tion of said wax I In testimony whereof I/ha'vehereunto set my hand in the presence of two witnesses. cnARnns' w.sHEvLm.
